bloging on a phone

Right now i am on daynas phone on moblie web because she has strait talk so she atomaticly comes with moblie web and last night i was setting up my blog where i could text posts to my blog from my grandmas phone but we have alltel and blog spot does not support alltel anymore because about a year ago verizion bought most of the alltels nationwide but there are a few in southern Illinois and so alot of stuff doesnt support alltel anymore and it gets frusterating sometimes
